As shown in fig. 1-5, an integration stainless steel liquid turbine flowmeter core, including casing 1, support 2, axle sleeve 3, connecting axle 4, impeller 5, preformed hole 6, casing 1 is the cylinder type, and inside cavity, and it has support 2 to be located to inlay in casing 1, the fixed welding flange of casing 1 left and right sides symmetry, the cylindric bolt head of fixedly connected with in the flange, and the bolt head is the cavity form, is located it has preformed hole 6 to be fixed opening on casing 1, set up the internal thread in the preformed hole 6.

Preformed hole 6 is convenient for external observation equipment, and the support is inlayed and is convenient for dismantle and change in the casing.

In this embodiment, the bracket 2 is rectangular, and a through rectangular placement groove is formed in the center of the bracket 2.

In this embodiment, the bracket 2 is fixed with fixing heads 7 at the left and right sides of the placement groove, and the fixing heads 7 and the bracket 2 are of an integral casting structure.

In this embodiment, fixed head 7 is cylindric, and is located fixed head 7 central point puts and has seted up circular shape centre bore, and the centre bore internal fixation is inlayed and is had axle sleeve 3, and axle sleeve 3 is the cylinder cavity cover.

In this embodiment, the fixed head 7 extends out of the outer frame of the bracket 2 by 30-40mm, and a conical plug is fixedly welded or in threaded connection with the tail end of the fixed head 7, and the plug is connected in a manner that the plug is matched with a ball bead through a shaft sleeve and then fixed.
